Philj I agree with you, it's not wise to go into debt over BTC and it wasn't before (but some people got lucky and won.)

Look at mtgox today, though, it's swinging wildly today with lots of volume.  So far today, anyone so inclined has been able to grow btc on mtgox.  Who knows how long these cycles will go on?  You don't need a high price for btc, you can also profit by growing them in the market.
